  • Fluid-filled vibration-damping device
    Patent number: 10895301
    Abstract: A fluid-filled vibration-damping device including: a pressure-receiving chamber with a non-compressible fluid filled therein; an equilibrium chamber with the non-compressible fluid filled therein; an orifice passage connecting the pressure-receiving chamber and the equilibrium chamber with each other; a relief configured to open a short-circuit passage by an action of a negative pressure occurring in the pressure-receiving chamber upon input of an impact load so as to connect the pressure-receiving chamber with the equilibrium chamber so that cavitation is suppressed; and at least one leak passage provided at a part of the short-circuit passage in the relief, the at least one leak passage keeping a communication state between the pressure-receiving chamber and the equilibrium chamber with a smaller passage cross section than that of the orifice passage, even when the short-circuit passage is not opened.
